Another ob ect resides in the provision of simple and efficient mean whereby the above mentioned object may one.

A further object resides in the provision of means whereby by the manipulation of a single element the liquid to the chamber and into association with t e solid material with which it co-operates to result in the electrolytic action.

A still further object resides in theparticular construction and arrangement of plarts hereinafter described and claimed and s casing" havin one containing solid .co nta1n1ng liquid.

so that when th chambers is broken the sure will force the liquid more efficiently into the previously evacuated chamber.

It will be readily understood from a consideration ofthe following description, when ta en in connection with the drawings, that modifications of in ,device may be made without departing from the spirit of the 1nvention. I

The invention is illustrated in the drawings, of which- Figure 1 represents a cross section of the a new and imb be achieved by any v i Specification of Letters Patent.

ause its associathe lower chamber. It is readily observable that this particular idea is applicable to any type of dry battery and that minor modifications necessary to apply it to one type or another are perfectly proper Without departing from the spirit of the invention.

By keeping the liq and, the solid material separate until the battery is to be used, the ordinary and usual deterioration of dry batteries is avoided, and they may be kept in storage when not in use for indefinite periods and still maintain their strength.

What I claim is:

1. A dry battery casing rality of spaced chambers, one of said chambers adapted to contain liquid and the other of said chambers adapted to contain solid material, a diaphragm between said chambers, a valve in said diaphragm, and means containing liquid,

\ chambers,

comprising a pluvalve When desired to cause for opening the the solid the association of the liquid with material.

' 2. A battery casing comprising a chamber an evacuated chamber containing solid material, a diaphragm separating said chambers, a valve in said diahragm, and means for opening the valve at will to permit introduction of the liquid in the one the other chamber. 3. A battery comprising a plurality of one of said chambers containing a liquid, another of said chambers containing the electrodes of the battery, an diaphragm separating the chambers, a glass tube sealed at one end into the diaphragm and extending into free end of the tube being closed, and a connection between the free end of the tube and the outside of the battery casing whereby When said connection is operated the glass tube is broken to admit the liquid in the one chamber into another chamber.
